2007 Overheating driving me crazy!!!
Water is radiator resivoir keeps getting hot and boiling over. I replaced the thermostat, and the resivoir cap but it kept getting hot and boiling over. The temp gauge never goes above the half way point. I finally broke down and took it to the shop. They ran a compression test and checked everything out. Said it was not the head gasket but didnt know what it was causing it. Said it could be the radiator fan, was working but said it was making a funny noise. I replaced the radiator fan this weekend and that didnt fix the problem! Im at a total loss here, if anyone has any ideas im listening..........

I'd check to see if the rad is getting ample flow of coolant through it. Had a Blazer kind of do the same thing and it was prob 70% clogged. Take top and bottom hoses off and run a garden hose through it. It should flow pretty well with no resistance.

I don't know, but I read about that in the Manual...when I installed the M90, I used a vacuum fill tool for the coolant. Reference this link:
